Mechanism of formation of the honeycomb-like structures by the regime of the reversing current (RC) in the second range
(Elsevier B.V., 2019)
Electrodeposition of copper in the hydrogen co-deposition range by the regime of reversing current (RC) in the second range has been investigated by determination of the average current efficiency for hydrogen evolution ...
Antimicrobial activity of metal oxide nanoparticles supported onto natural clinoptilolite
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The antimicrobial activity of Cu2O, ZnO and NiO nanoparticles supported onto natural clinoptilolite was investigated in the secondary effluent under dark conditions. After 24 h of contact the Cu2O and ZnO nanoparticles ...
Preparation and Characterisation of Novel Biodegradable Material Based on Chitosan and Poly(Itaconic Acid) as Adsorbent for Removal of Reactive Orange 16 Dye from Wastewater
(Springer Int Publishing Ag, Cham, 2015)
Environmental protection has been a topic of great interest in recent years. Discharging azo dyes in aquatic systems contaminates water and causes serious ecological problems. Azo dyes are bio-accumulative, and, due to ...
A kinetic study of the release of vanillin encapsulated in Carnauba wax microcapsules
(Elsevier Sci Ltd, Oxford, 2012)
Thermal release of vanillin encapsulated in Carnauba wax microcapsules was studied by isothermal thermogravimetric analysis at 443, 453, 473, and 483 K. The thermal analysis data were analyzed kinetically and it was found ...
Effects of additives on nickel (ii)-chloride hydrogen reduction for production of nanocomposite catalysts
(Editura Stiintifica Fmr, Bucharest, 2012)
Catalysts based on nickel, as active component, exhibit suitable properties in various heterogeneous catalysis processes; however, they quickly deactivate due to deposits formation during exploitation and sintering at ...
Solubility in K+-Na+-Mg (4) (2-) aqueous solution at T=298.15 K
(Maik Nauka/Interperiodica/Springer, New York, 2013)
In the salt solubility predictions for K+-Na+-Mg (4) (2-) aqueous solution the treatment of thermodynamic data of three-component systems at T = 298.15 K involved the application of the Extended Pitzer's ion-interaction ...
Initial corrosion protection of Zn-Mn alloys electrodeposited from alkaline solution
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The effects of a deposition current density (c.d.) on the corrosion behaviour of Zn-Mn alloy coatings, deposited from alkaline pyrophosphate solution, were investigated by atomic absorption spectrophotometry (AAS), X-ray ...
Phase transition at subcritical and supercritical conditions of triglycerides methanolysis
(Elsevier, Amsterdam, 2010)
The analysis of phase equilibrium between methanol and glycerides during methyl esters of fatty acids (FAME or biodiesel) synthesis at high pressure and temperature is very important for describing the kinetic and process ...
Optimization Approach for Continuous Catalytic Regenerative Reformer Processes
(Amer Chemical Soc, Washington, 2010)
The new approach for simulation and optimization of a continuous catalytic regenerative (CCR) reformer process is proposed. Typical CCR reforming processes consist of three to four reactors with recycle. The reaction ...
Fast evaluation of periodic operation of a heterogeneous reactor based on nonlinear frequency response analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The concept of higher-order frequency response functions (FRFs), which is based on Volterra series representation of nonlineral systems, is used to analyse the time-average performance of a perfectly mixed reactor subject ...
